Description

Technical Field

[0001] This utility model relates to the technical field of yarn feeding mechanism for weft knitting machines, specifically a quantitative yarn feeding mechanism for weft knitting machines for knitted fabrics. Background Technology

[0002] Weft-knitted fabrics are made from low-elastic polyester yarn or profiled polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., using plain knit, modified plain knit, rib plain knit, double rib plain knit, jacquard, terry knit, etc., woven on various weft knitting machines. When weaving weft-knitted fabrics using a weft knitting machine, the yarn needs to be continuously fed.

[0003] For example, Chinese patent CN213833963U discloses a yarn self-supply mechanism for weft-knitted fabrics, which includes a workbench. Fixed seats are sequentially bolted to the left side of the top of the workbench from front to back, and fixed columns are bolted to the top of the fixed seats. A yarn spool is movably connected to the surface of the fixed column, and the yarn body is wound on the surface of the yarn spool. A combing mechanism is provided on the left side of the top of the workbench. This invention, through the cooperation of a combing mechanism, facilitates the user in limiting the position of the yarn body, preventing it from shaking and causing tangling and knotting that would affect the fabric weaving process. The cooperation of the second support plate, fixed plate, first spring, movable plate, and fixed ring allows the user to easily adjust the tension of the yarn body, preventing it from shaking and keeping the yarn bodies parallel to each other. This solves the problem that traditional weft knitting fabric yarn self-supply mechanisms cannot effectively manage the yarn. Traditional weft knitting machine yarn supply mechanisms have fixed numbers and positions of rollers, making it impossible to adjust the spacing between yarn bobbins. Different sizes of yarn bobbins occupy different amounts of space, making adjustment impossible as needed. Therefore, this invention proposes a quantitative yarn supply mechanism for weft knitting machines to solve the above problems. Utility Model Content
